Description

description

The invention relates to a system for establishing a peripheral frame for a building opening and a frame

composed of the components of the system.

A peripheral frame for a window opening can also be referred to as a soffit frame or soffit cladding and is a frame which is present on the building side around a window and protrudes over the outer wall, in particular the thermal insulation layer and plaster layer or cladding of the facade, of the building. In this context, window also means a French balcony. The frame includes a window sill or a window sill, two side elements and a top element, which the window sill or the

window sill opposite.

According to the prior art, cladding of window reveals in the form of sheet metal elements or aluminum profiles are known, which are attached to the frame of the window and line the existing reveal of the wall. There is usually a conventional window sill and the cladding elements additionally cover the side walls and the upper surface of the window reveal, so that there is no unified system or unified or uninterrupted frame. The sheet metal elements or aluminum profiles of the reveal elements can protrude slightly from the facade of the building, with the window sill usually protruding further than this. It is also disadvantageous that the load dissipation takes place at least partially on the window frame. In some solutions, metal elements are also screwed to the masonry with metal mounting brackets, with the brackets being attached directly to the metal element and to the wall, so that one disadvantageous

thermal bridge results.

The object on which the invention is based is to provide an improved frame for a building opening

place.

To solve the task, a system according to claim 1

suggested.

The system includes a soffit frame, which is composed of soffit elements and assembly elements and cladding elements, in particular made of sheet metal. The cladding elements preferably include cover elements, which are present on the inside of the frame and connecting elements, which are on the outside

frame available.

The reveal elements are preferably made of heat-insulating material, in particular a rigid foam, so that it is advantageous

Thermal bridges in the area of the reveals can be reduced.

The frame or the soffit element are arranged circumferentially around the building opening, with the soffit elements adjoining one another directly, so that the building opening is of one

Border of thermal insulation material is surrounded.

Force is introduced through the installation elements, with which the reveal elements are fastened to the surface of the wall or building wall that is parallel to the building opening

mainly in the wall or building wall.

Due to the two-layer structure with inner reveal elements and outer cover elements, which are preferably glued to the reveal elements over a large area, it is possible for the frame to overhang far beyond the facade.

which increases the design freedom for the planner of a building.

Thanks to the modular system, this can be provided in the required dimensions and shape without a great deal of adjustment effort, which also increases the freedom of design for

increases the planner of a building.

Different types of soffit elements are preferred. A kit usually contains two or three different soffit elements, with the side soffit elements usually being identical. The upper and lower reveal element can also be identical to each other

present.

Page 2

One type preferably has a parallelogram cross-section. Another type has a rectangular cross-section. The cross-section can also be wedge-shaped, trapezoidal or triangular, depending on

Design request of the planner of the building.

It is preferred that the lower soffit member has an upper surface that slopes away from the building

runs.

It is preferred that the upper deck member has a top surface

has, which runs downhill from the building.

The lower surface of each soffit element can be parallel to the upper surface to form a parallelogram, or inclined to the upper surface to form a trapezoid or

triangular present.

Preferably, soffit members of parallelogram cross-section form the bottom and top members of the soffit frame and soffit members of rectangular cross-section form the side members of the soffit frame. When installed, the reveal elements each face the building with a narrow longitudinal edge. In the case of a trapezoidal cross section, the broader of the two parallel side surfaces preferably faces the building. In the case of a triangular cross section, the shortest side surface preferably faces the building. The area facing the building rests against the building when the frame is assembled and is fixed against the building by the assembly elements. In addition, assembly adhesive or assembly foam can be used

be used.

Several mounting elements are each attached to one of the flat sides of the respective reveal element. The mounting elements for the soffit elements with a parallelogram cross-section have a sloping side edge which abuts the soffit element. The mounting elements are in the assembled state in each case

Arranged on the outside of the reveal elements. The outside is

is turned away.

The mounting elements are preferably screwed or glued to the reveal elements. Preferably, the assembly elements are positioned on the subsequent outside of the respective reveal element and fixed to it with two screws from the inside through the respective reveal element. The mounting elements have a surface that faces the building and is at a distance from the side surface of the respective reveal element that faces the building. During assembly, this gap is used to compensate for unevenness in the building wall, in particular concrete or brick wall. During assembly, small plates or wedges are positioned in the gap,

to bridge this.

The assembly elements preferably have openings for fastening means, in particular screws. The openings

run towards the building.

The assembly elements can preferably be freely positioned along the reveal elements. The reveal elements are accordingly

cut to the length and height of the window opening.

The reveal elements preferably consist of a heat-insulating material, particularly preferably of a rigid foam, in particular of PUR rigid foam, polyisocyanurate foam (PIR foam) or PET foam, or a mixture of these. For example, Purenit® (registered trademark of puren gmbh) is suitable. The material is preferably in sheet form. The frame material counteracts thermal bridges in the reveal area on the one hand and dampens driving rain noise on the other. The material is also easy to cut or saw and is

screw tight.

The mounting elements are preferably made of a heat-insulating material, particularly preferably of a hard foam, in particular

made of PUR rigid foam, polyisocyanurate foam (PIR foam) or PET

page 4

foam, or a mixture of these. For example

Purenit® (registered trademark of puren gmbh).

During assembly, the lower reveal element is assembled first, which is the length of the window frame plus twice the lateral gap and plus twice the thickness of a side element. The lower reveal element is mounted with a lower gap below the window frame. For this purpose, a spacer strip can be placed on the lower reveal element so that the spacer strip determines the gap dimension when it is held against the window frame from below. In this position, the soffit element using the

Mounting elements attached to the wall.

The next step is to place the two side reveal panels by placing them perpendicular to opposite ends of the bottom reveal panel, again using a spacer bar to create the lateral gap to the window frame. In this position, the side reveal elements with help

of the mounting elements attached to the wall.

Finally, the top reveal panel is placed above the side reveal panels and against the wall

fastened.

When installing the soffit elements, sealing tapes are used in the area between the soffit elements and the gap around the

window frame attached.

When the four soffit panels are assembled, tape sealing tapes can be applied to the joint areas of the soffit panels. Highly flexible butyl tapes are preferred

to ensure sealing.

If the reveal elements are sealed to each other and to the wall around the window frame, then the

Cladding elements are attached to the reveal elements.

The cladding elements cover the reveal elements on the surfaces that will later be exposed on the building. Two cladding elements in the form of one are preferred for each reveal element

Cover element and a connection element available.

In the inner corner areas of the frame there are always two cover elements, usually at an angle of 90 degrees to one another, with a gap being present between the cover elements. The building opening and the soffit frame usually have a rectangular opening area. However, the reveal frame can also have a different shape, for example a trapezoidal shape with a width that tapers upwards or downwards, so that between the lower and upper reveal element and the respective

Side element is an acute or obtuse angle.

The cover element elements each have a rear fastening web which bears against the wall. The fastening webs preferably have elongated holes in order to screw them to the wall or a window sill connection profile

The cladding elements surround the front of the building

facing away from the longitudinal sides of the reveal elements.

The cover element and the connection element of the respective frame element are preferably hooked into one another on the outer edge of the long side of the frame facing away from the building. The two elements are preferably not screwed together. Thus, thermally induced changes in length of the

Cover elements and the connection elements take place.

By hooking the cover elements and connecting elements, a modular system is created that is suitable for any type of wall opening. Both the cover elements and the connecting elements can be cut from a sheet metal material in the required length and width and bent with it

be provided with the required webs and engagement sections.

The interlocking of the cover elements and the connection elements

takes place preferably via engagement sections, which
